A fitted pair of shoes is important to the development of the bones in a child's foot. The need for supportive, specialized footwear only grows when a boy or girl participates in athletic programs, such as running, soccer, basketball or football, that place additional demands on growing feet. When shopping for children's sport shoes and cleats, it's important to buy shoes of the proper size and with as much support as possible to assist with ankle stabilization and impact absorption. A quality sneaker should be breathable to prevent bacteria build-up after sweaty practices and fit properly with approximately the space of a thumbnail between the big toe and tip of the shoe. For specialty cases, such as larger feet, opt for wide sizes and additional cushioning when added body weight increases strain on the foot.
